1. A receiving unit that receives one or more data signals, the one or more data signals having common mode voltage at the receiving unit, the receiving unit comprising:

  • a voltage driver that supplies a compensated voltage in response to a feedback signal;

    wherein the compensated voltage is distributed to produce a distributed voltage; and

    a feedback unit that is responsive to the distributed voltage and to at least one data signal of the one or more data signals;

    wherein the feedback unit controls the feedback signal to establish the distributed voltage at a value that is approximately equal to the common mode voltage of the at least one data signal of the one or more data signals; and

    wherein the feedback unit is inactive and is not receiving the at least one data signal of the one or more data signals during an operational phase of the receiving unit.
